Hi,
before i create a socket at a udp port, i need to check if it is already in use. Any idea how to do it..

Hi,
Java doesn't provide that type of API (Correct me if I am Wrong). But i would say try to open the datagram Socket within a Try Catch block and catch for Bind exception then you can implement what ever is your requirement.
hope this helps

Hi,
JDK1.4 provids an API to check whether the socket is bound or not.
I didn't use this but it may be worth checking it.
